PURE Bioscience Receives Order for Shipment of PURE� Hard Surface Disinfectant to Asia

Superior SDC-Based, Non-Toxic, Broad-Spectrum Antimicrobial Offers Kill Times as Fast as 30 Seconds

RANCHO CUCAMONGA, Calif.–(BUSINESS WIRE)–PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented non-toxic silver dihydrogen citrate (SDC) antimicrobial, today announced it received a purchase order to ship EPA-registered PURE^® Hard Surface disinfectant to Harmony Bioscience, a distributor in Asia with various locations. Harmony Bioscience holds Asian import and sales permits for PURE Hard Surface disinfectant. PURE Chairman and CEO Tom Y. Lee is an affiliate of Harmony Bioscience.

The order is for RTU (ready-to-use) and is expected to ship by sea in early April to Harmony International Holdings Co., Ltd. (Hong Kong). From there, PURE Hard Surface disinfectant will then be redistributed to Taiwan Harmony Eco-Science Col, Ltd. and Guangzhou Harmony Eco-Science Co., Ltd. (China). The product will then be resold for institutional, janitorial, consumer, hospital and school use. A smaller initial shipment was sent by air last week to Hong Kong.

Lee said, “We are pleased that the years of work to prepare us to expand our domestic sales of our powerful and non-toxic antimicrobial solution into the Asian market are beginning to pay off. We are hopeful that this is the first of what could become future, recurring orders.

“PURE Hard Surface disinfectant – which has kill times as fast as 30 seconds and is also registered for use on food contact surfaces – is being used in the U.S. by food transport companies, restaurants, produce processors and more than 100 processors/manufactures as a proven and effective disinfection solution,” Lee concluded.

Since 2011, the U.S. EPA has registered PURE Hard Surface disinfectant to be effective on a wide range of pathogens, including:

• Human Coronavirus, Influenza, Listeria, Norovirus, Salmonella and E. coli, and in a wide variety of environments, including:
• Medical, food processing, food service, public transportation, home/children/pets, janitorial & institutional (schools, office buildings, prisons, government installations, etc.) and other areas.
